Creates a LocalSolrQueryRequest based on variable args; for
historical reasons, this method has some peculiar behavior:
If there is a single arg, then it is treated as the "q"

string along with "qt", "start", and "rows" params (based
on the qtype, start, and limit properties of this factory)
along with any other default "args" set on this factory.
